My apologies for the mai"Personal invitetion". In fact when my computer was on my 9 yr old grand son sent this when my mail was on and I went to take delivery of a curior post. When i discovered today, I asked him and he confessed the truth. He sent this across to many.

KINDLY ignore

Anyone have an electronic copy of some biogas burners and biogas light

designs handy?

Can do the hard and dirty, am more interested in refinements such as

adapting for biogas/air mixtures and "proven" tricks/technologies.

Would appreciate it.

Dear Yvonne,

For Dry Fermentation for developing country, I suppose the substrates needs 

to be treated with composting process before disposing or use it as soil 

conditioner( to get rid of the smell and to dry it further to reduce the 

weight and save transportation cost ).

One can actually install an air blower and install some pipes under the 

floor to carry out aeration process after completion of the anaerobic 

process, that will also solve the problem about when you open the door of 

the digester.

Hopes it will answer your question.

A request from another group I am thinking someone from this group could reply. 

Thanks

Frank

Dear List-Serve Fellows,

The non-profit I work for has been convinced for several years of the

pivotal importance of compost, and of the superiority of decentralized

approaches to organic waste processing (to minimize transportation

costs, energy use and emissions, and to maximize the appeal of

participation). We are open to organics processing that produces energy

as well as compost. However, we are concerned that the price tags of

most anaerobic digester may require a scale of operation that prohibits

decentralized approaches, and may place compost in a subordinate

position, at best. 

Has anyone worked on, or does any know of, low-cost, small-scale

anaerobic digester systems -- rural and/or urban; 

ones that may be better components, better partners, in a decentralized

strategy?

Thank you very much.
